BOTTLE STOPPAER.

Application filed March 2, 1922.

T0 all 'Lu/om t may concern.

Be it known that we, JOHN F. BORNE and GEORGE A. GALLowAY, citizens ofthe United States, residing at Buffalo, in the county ot Erie and Stateof New York, have invented new and useful lmprovements in BottleStoppers, of which the following is a specification.

rIhis invention relates to a stopper for hermetically sealing bottlesand similar containers, and more particularly stoppers of this typehaving an elastic plug which is expanded against the neck-wall of thebottle by compressing the plug longitudinally.

The object of the invention is to provide an improved stopper of thischaracter having simple and reliable means for preventing its plug fromslipping and turning in the neck of the container in expanding it.

ln the accompanying drawings: Figure 1 is a sectional elevation of thestopper in position in the neck of a bottle. Figure 2 is a perspectiveview of the washer interposed between the plug and the clamping nut.Figure 3 is a bottom plan view thereof.

Similar characters oit' reference indicate corresponding partsthroughout the several views.

10 indicates the body or plug of the stopper which is constructed ofrubber or similar elastic or expansible material, and which is of theproper size to it the neck of the bottle 11. Passing centrally andloosely through this plug is a. 4bolt 12 having a head 13 at its lowerend, while its upper end is provided with a suitable cla1nping member,such as a wing nut 111. A washer 15 may be interposed between the headof said bolt and the bottom of the plug, and a washer or cap plate 16 isarranged between the top of said plug and the clamping nut, as shown inFig. 1. After inserting the plug into the neck of the bottle, the nut isscrewed down on the bolt 12 to f compress the plug and expand it againstthe wall of the neck to form a tight joint.

Means are provided for preventing the plug 10 from slipping or turningin the bottle-neck during the operation of tightening and expanding it,this slippage being liable to occur particularly if the neck or the plugbe wet. The preferred means for holding Serial No. 540,522.

the plug against such movement consist ot one or more arms or fingerpieces 17 depending from the edge of the washer 16 and overhanging theupper end of the bottleneck. As shown, these stop-arms are preierablyarranged on diametrically-opposite sides of said upper washer. Bygrasping these arms with one hand while tightening the clamping nut 14with the other, the part or washer 16 is firmly held against turning andowing to the frictio-nal contact between this washer and the plug, thelatter is also effectually held against turning or slipping, therebypermitting the plug to be properly expanded within the neck of thebottle to hermetically seal the same. These holding arms also preventturning of the plug in loosening tle nut, thus facilitating the releaseof the If desired, the underside of the washer 16 which contacts with,the plug may be roughened or providedv with projections, as shown at 18in Figs. 1 and 3. These proj ections embed themselves in the top of theplug and assist in preventing it from turn-` ing relatively to thewasher and the bottle. In tightening the nut or clamping member 14, thebolt 12 slides upwardly inthe opening of the washer 16. To facilitatethis operation and prevent binding or undue friction between the boltand the edge of said opening, the latter is smooth and circular and thebolt is cylindrical, las shown, or at least that part oi' the bolt whichpasses through the opening is of that form.

We claim as our invention:

1. A bottle stopper, comprising an expa-nsible plug, a bolt extendingthrough said plug and provided at its upper end with a clampino' member,the lower end of said bolt having ahead engaging the lower end of saidplug, a cap-plate interposed between said clamping member and the upperend of said plug and having a linger-piece, and means carried by saidcap-plate and interlockingwith said plug for holding the latter fromrotation in the bottle-neck in tightening said clamping member.

2. A bottle-stopper, comprising an expansible plug, a bolt extendingthrough said plug and provided at its upper end with a clamping member,the lower end of said bolt having a head engaging the lower end of saidplug, a' cap-plate interposed between said clamping member and the upperend of said plug and provided with a lingerpieoe, said Cap-plate havinga circular opening for the passage of said bolt and means interlockingWith said plug for holding' the latter from rotation in the neck of thebottle in tightening said clamping member', the portion of said boltwhich passes through l0 said opening being cylindrical.
